Donald Michael Chorney was last seen on July 1, 1995, at Keys Lake Campground near Grassy Narrows after leaving the campsite to go for a boat ride. He was described as 71 inches tall with a heavy build. His boat was later recovered, but Donald himself was never found.

Investigators have since presumed he drowned in Keys Lake, but no body was recovered and the circumstances of his disappearance remain unresolved. The lack of definitive recovery has left the family without closure.

If anyone was at Keys Lake or Grassy Narrows on or around July 1, 1995, or has information about a boat found or moved in that area at the time, please come forward.
